Description

Technical Field

[0001] This utility model relates to the field of rail transport vehicle technology, and in particular to a rail transport vehicle for ships. Background Technology

[0002] Rail transport vehicles are transport vehicles that travel on specific tracks. They come in various types and have different uses, and can be designed and manufactured to meet different needs. Rail transport vehicles are mainly used to transport goods and personnel on tracks. They typically consist of a frame, wheels, drive system, and control system, and can be powered by electric, hydraulic, or other means. Marine rail transport vehicles refer to vehicles used on ships that travel along tracks, primarily for transporting goods or materials.

[0003] In the prior art, a rail conveyor for transporting feed portions, according to patent publication number CN219313801U, includes a transport vehicle with a transport rail at the bottom and a transport platform on top. A pallet is mounted on the top surface of the transport platform, and an expansion platform is provided in a groove inside the transport platform. Support wheels are provided on both sides of the expansion platform, thus eliminating the need for manual transport, reducing the labor force of workers, and improving the efficiency of feed transport. However, traditional ship rails consist of only two independent rigid rails directly fixed to the deck. This structure lacks overall stability when subjected to the huge swaying and impact of ship navigation, and is prone to deformation or misalignment. There is also a lack of effective buffer device between the rails and the vehicle body, and the impact force is directly transmitted to the vehicle body and cargo, posing a safety hazard. In addition, the wheels of the existing conveyor are directly connected to the vehicle body through rigid brackets. When the ship sways, this rigid connection will cause the vehicle body to run unevenly and generate violent vibrations, which not only affects the safety of cargo, but also easily damages the wheels and rails.

This structure lacks overall stability when subjected to the huge swaying and impact of the ship during navigation, and is prone to deformation or misalignment. There is also a lack of effective buffer device between the rails and the vehicle body, and the impact force is directly transmitted to the vehicle body and cargo, posing a safety hazard. In addition, the wheels of the existing transport vehicles are directly connected to the vehicle body through rigid brackets. When the ship sways, this rigid connection will cause the vehicle body to run unevenly and generate violent vibrations, which not only affects the safety of cargo, but also easily damages the wheels and rails.

[0005] To achieve the above objectives, a rail transport vehicle for ships is provided, comprising a first rail frame, a second rail frame mirror-arranged along the center of the first rail frame, and multiple supporting base plates arrayed and fixed at the bottom of both the first and second rail frames. Multiple buffer structures are provided between the inner sides of the first and second rail frames, with each buffer structure corresponding to one of the three supporting base plates at the bottom of the rail frame. Each buffer structure includes a buffer outer plate, and the multiple buffer outer plates are disposed inside the corresponding supporting base plates. Reinforcing screw holes are provided on the outer sides of the multiple buffer outer plates, penetrating into the interior of the corresponding supporting base plates. A buffer telescopic member is fixed between two adjacent buffer outer plates along the longitudinal direction.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figures 1-4This utility model discloses a ship rail transport vehicle, comprising a first rail frame 1, a second rail frame 2 mirror-imagely arranged along the center of the first rail frame 1, and multiple supporting base plates 3 fixedly arranged in an array at the bottom of both the first rail frame 1 and the second rail frame 2. Multiple buffer structures are arranged between the inner sides of the first rail frame 1 and the second rail frame 2, with three buffer structures corresponding to the three supporting base plates 3 at the bottom of the rail frames. Each buffer structure includes a buffer outer plate 4, with multiple buffer outer plates 4 disposed inside the corresponding supporting base plates 3, and each buffer outer plate 4 having reinforcing screw holes 5 extending into the interior of the corresponding supporting base plate 3. A buffer telescopic member 6 is fixed between two adjacent buffer outer plates 4 along the longitudinal direction. In the prior art, traditional ship rails consist of only two independent rigid rails directly fixed to the deck. This structure is susceptible to damage when subjected to the enormous swaying and impacts during ship navigation. Lacking overall stability, the existing transport vehicles are prone to deformation or misalignment. Furthermore, the lack of effective buffering devices between the track and the vehicle body means that impact forces are directly transmitted to the vehicle and cargo, posing safety hazards. The wheels of the existing transport vehicles are directly connected to the vehicle body via rigid supports. When the ship rocks, this rigid connection causes the vehicle to run unevenly, generating severe vibrations that not only affect cargo safety but also easily damage the wheels and tracks. To address these issues, an integral track base consisting of a first track frame 1 and a second track frame 2 can be adopted. A buffer structure including a buffer outer plate 4 and a buffer telescopic component 6 is installed between the two frames, forming a track system with good overall rigidity and torsional resistance. This design can effectively absorb and disperse the enormous impact energy generated by the ship's rocking in wind and waves, preventing track deformation or misalignment, greatly improving the stability and service life of the track system under harsh sea conditions, and protecting the safety of the transport vehicles and cargo.

[0019] Two transport wheels 7 are fitted into the inner grooves of both the first track frame 1 and the second track frame 2. Support plates 8 are rotatably connected to the tops of multiple transport wheels 7, and transport vehicle frames 9 are bolted to the tops of multiple support plates 8. A transport vehicle is electrically connected to the bottom of the transport vehicle frame 9. The inner walls of the transport vehicle frame 9 are smooth all around. The transport vehicle frame 9 is connected to the transport wheels 7 through the support plates 8, forming an independent walking module. This modular design not only facilitates installation and maintenance, but also effectively separates the walking mechanism from the load-bearing mechanism. This ensures that the vibration transmitted by the track is initially attenuated by the buffer structure and is not directly transmitted to the vehicle body, thus achieving secondary shock absorption and ensuring the stability of the transportation process.

[0020] A partition 10 is fixed at the center of the inner side of the conveyor frame 9. The outer surface of the partition 10 is smooth, which can divide the cargo hold into different areas, effectively preventing collisions, slippage and mixing of goods during the ship's swaying. It is especially suitable for transporting multiple or fragile items at the same time, improving the standardization and safety of transportation.

[0021] Multiple buffer outer plates 4 are made of rubber. On the one hand, the high elasticity and damping properties of rubber further enhance the buffering and shock absorption effect of the entire track system. On the other hand, rubber has good corrosion resistance and can resist the erosion of the high-salt and high-humidity marine environment, thus extending the service life of key buffer components.

[0022] A pressure sensor 11 is fixed to the front end of the conveyor frame 9. The pressure sensor 11 is electrically connected to external equipment. The pressure sensor 11 can be used as a collision detection device. When the front end of the vehicle body comes into contact with an obstacle, the sensor can quickly send a signal to enable the control system to brake in time and avoid an accident.

[0023] The inner walls of the first track frame 1 and the second track frame 2 are all smooth. Both the first track frame 1 and the second track frame 2 are welded from low-alloy high-strength steel. The low-alloy high-strength steel ensures that the track frame has sufficient strength and toughness under harsh sea conditions, while also helping to reduce the overall structural weight. The smooth inner wall surface reduces the frictional resistance of the transport wheel 7 during operation, making pushing easier, running more smoothly, and reducing noise and power loss.

[0024] Reinforcing ribs 12 are fixed between the left and right ends of the inner side of the conveyor frame 9. The reinforcing ribs 12 can significantly improve the bending and torsional resistance of the conveyor frame 9, prevent the frame from deforming under heavy load, and ensure the long-term reliability and load-bearing capacity of the structure.

[0025] A ventilation hole 13 is provided at the front end of the outer side of the conveyor frame 9, and the ventilation hole 13 extends to the rear end of the outer side of the conveyor frame 9. A cover plate 14 is fixed to the top of the conveyor frame 9 by bolts. The ventilation hole 13 allows air to circulate inside the frame, which helps to dissipate the heat generated by electronic devices (such as batteries and controllers) and prevents moisture accumulation, keeping the inside dry. The bolt-fixed cover plate 14 allows the top of the vehicle body to be opened easily, which can be used for loading and unloading goods, as well as for inspecting and maintaining the equipment inside the vehicle body, thus improving the ease of use.

[0026] Working Principle: First, a designated location is selected. Then, the entire device is fixed through the positioning screw holes on the top surface of multiple support base plates 3, and material rail transport begins. When the ship sways and experiences impacts in wind and waves, the impact force is first transmitted through the support base plates 3 to the rigid rail base composed of the first rail frame 1 and the second rail frame 2. Then, the enormous impact energy acting on the rail base is effectively absorbed by the buffer structure located between the two frames. Specifically, the buffer expansion joint 6, as the core buffer element, undergoes compression or tensile deformation, directly dissipating most of the impact kinetic energy. Simultaneously, the rubber buffer outer plate 4 utilizes its high elasticity and damping characteristics to provide additional buffering and vibration isolation effects, collectively transforming the severe impact into gentle, controllable micro-movements, protecting the safety of the transport vehicle and goods, and preventing the rail itself from deforming or misaligning due to long-term impact. The transport vehicle frame 9 is connected by support plates... 8 connects to the transport wheel 7 to form a relatively independent walking module. The transport vehicle is electrically connected, causing the transport wheel 7 to roll in the groove of the track frame with a smooth inner wall. The running resistance is small, realizing material transportation and achieving secondary shock absorption. This ensures the stability and smoothness of the transport vehicle running on the track. During transportation, the partition 10 in the center of the inner side of the transport vehicle frame 9 separates the cargo compartment, effectively preventing the cargo from colliding, mixing or being damaged due to the swaying of the ship. The pressure sensor 11 fixed at the front end of the transport vehicle frame 9 monitors the contact situation in front in real time. Once a collision with an obstacle occurs, it can immediately send a signal to stop the vehicle, realizing active safety protection. In addition, the reinforcing rib 12 ensures the structural strength of the frame under heavy load, the ventilation hole 13 helps the internal heat dissipation and moisture prevention, and the openable cover 14 facilitates the loading and unloading of cargo and the maintenance of internal equipment, thereby improving the use effect of the rail transport vehicle.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
